LATCH FOR TEMPORARY BINDERS.

Specicaton of Letters Patent.

Application filed January 14:, 1905. Serial No. 241,056.

To all whom t may concern.-

Be it known that I, EMORY A. TRUssELL, a citizen of the United States,residing in the city of St. Louis, in the State of Missouri, haveinvented certain new and useful Improvements in Latches for TemporaryBinders, of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, forming part of thisspecification.

My invention relates to a latch for uniting the hinged sections of atemporary binderback, whereby the back sections may be swung apart ontheir connecting-hinges to separate the sheet-receiving arches carriedby said sections and to provide for the retention of the back-sectionswhen moved together to hold the sheets confined on the prongs.

Figure I is a perspective view of the central portion of my binder withthev back-seetions shown swung apart. Fig. II is an enlarged face viewof the central portion of the binder at one end with the back-sectionsheld closed by4 my latch. Fig. III is a cross-section taken on line IIIIII, Fig. II. Fig. IV is a longitudinal section taken on line IV IV,Fig. II.

l designates parts of the covers of my binder, and 2 designates thesections of 'the binder-back which are united by a hinge, preferablyproduced as an integral part or parts of the binder-back.

I designates prong-carrying plates secured to the back-sections. 2 and 5are prongs projecting from these plates.

No invention per se is herein claimed for the parts just described. i

6 designates a catch-plate fixed to one of the back-sections 2 andprovided with atongue 7 projecting therefrom in the direction of theother back-section, the said tongue having an inturned lip 8. 9 is alatch-plate secured to the second back-section and having an upturnedapertured keeper 10 projecting therefrom at its forward end and providednear its rear end with a stud 1l, projecting upwardly therefrom, both ofthe members 10 and 11 being struck from the latch-plate and integraltherewith. In the latch-plate 9 and eX- tending longitudinally thereofis a slot 9, that is in alinement with the keeper 10 and stud Il.

12 is a catch-arm that is seated in the keeper 10 and has its forwardend projecting through said keeper to furnish a finger-receiving portion13. The rear end of this catch-arm is notched to receive the stud l1,which lits thereinto and serves to hold the catch-arm from rearward andoutward movement, the said stud being bent forwardly over the arm toprevent the outward movement.

14 is a spring secured to the catch-arm l2 at its rear sideand'extending forwardly from its point of attachment to the arm. Thisspring occupiesa position in the latch-plate slot 9 and its forward endextends into bearing with the latch-plate at the front end of said slot,thereby preventing forward movement of the latch-arm, to which it isattached.

It will be seen in the practical use of my latch that when the binderback-sections are brought together the tongue 7 of the catchplate 6 willpass over the latch-arm 12, carried by the latch-plate 9, and the lip ofthe catch-plate tongue will engage the latch-arm to prevent separationof the catch-plate and latch-plate, this result being due to thecatcharm being held in a projected position by the spring 14: beneathit. When it is desired to separate the catch-plate tongue from thelatcharm, it is only necessary to depress thelforward end of saidlatch-arm by pressure upon the finger portion 13 in order that saidtongue may be separated from the arm.

I claim as my inventionl. The combination with the hinged backsectionsof a binder, of a latch-plate carried by one of said sections, acatch-arm having one of its ends rockingly fitted to said plate, aspring having one of its ends secured to said catch-arm and lits otherend resting beneath said catch-arm, and a catch-arm carried by the otherback-section and having a tongue arranged for engagement with saidfirst-named catch-arm when the back-sections are brought together,substantially as set forth.

2. The combination with the hinged backsections of abinder, ofa-latch-plate carried by one of said sections, a catch-arm having itsinner end rockingly held to said plate, aspring secured to saidcatch-arm adjacent to the point of its connection with said plate; thesaid spring having a free end resting beneath said catch -arm andbearing at its termination against the plate to prevent its forwardmovement, and a catch-arm carried by the other IOC back-section andhaving a tongue arranged to engage said first-named catch-arm when theback-section/s are moved toward each other, substantially as set forth.

3. The combination With the hinged backsections of a binder, of alatch-plate carried by one of said Sections and provided with a stud, acatch-arm having a notch in its inner end and loosely fitted to saidstud, a spring secured to said catch-arm at its lower side adjacent tosaid stud; the said spring having its free end arranged to rest' beneaththe catcharm and bearing at its termination against said latch-plate toprevent disconnection of the plate from said stud, and a catch-armcarried by the other back-Section and havinga tongue arranged to engagesaid first-named catch-arm when the back-sections are Imoved toward eachother. substantially as set forth.

4. The combination With the hinged backsections of a binder, of alatch-plate carried by one of said sections, a catch-arm rockinglyfitted to said latch-plate at its inner end, a spring having one of itsends secured to said catch-arm and its other end resting against saidback-section, and a catch-arm extending longitudinally of the otherback-section and having a tongue extending transversely thereto providedwith an inturned lip adapted to engage said first-named catch-arm Whenthe back-sections are moved toward each other. substantially as Setforth.

5. The combinationwith a binder-back consisting of sections hingedtogether; of a slotted latch-plate secured to one of said sections andprovided with an outturned apertured keeper and a stud, a catch-armsecured at one end by said stud and having its other end projectingthrough said keeper. aspring secured to said catch-arm and extendingforwardly in the slot in said latch-plate, and a catch-plate secured tothe other back-section and having a tongue arranged for engagement withsaid catch-arm when said latch -plate and catch plate are movedtogether, substantially as set forth.
